fastify VS Hapi

For example, Fastify removed the instanceof operatorfrom its codebase because it was causing problems for those developers that rely on jest as a testing framework.

Both are frameworks but NextJs is for Forntend (web app in browser that use ReactJs under the hood) and NestJs is for Backend (server app running on a server witch use Express or Fastify). The only thing similar between them is the typed language in which they were written.

Restify & Fastify Hapi

Let's create a sample Node API project we can work with throughout to build a new docker image. We will leverage Fastify to create an API that we configure via the fastify-cli.

Fastify

In setting out to build this service, we wanted to use gRPC for its APIs. We’ve been reaching for REST when building APIs so far, primarily out of necessity, i.e., our public APIs needed auto-generated client SDKs and docs for developers working with them. We built those APIs with Fastify and Typebox but felt burned by a code-first approach to generating an OpenAPI spec. I’ll spare you the details and save that experience/learning for another article. Suffice it to say we love gRPC’s schema-first approach. This blog post summarizes our feelings well

Fastify – Fast and Low overhead web framework

Custom Functions are powered by Fastify (a light-weight Node.js framework that claims to be faster than Express.js), so they’re extremely flexible.

I tend to use hapi (https://hapi.dev) instead of Express if I need to write a quick backend for something these days.

Fastify looks nice too but I haven't used it.

Been burnt by full-stack frameworks in the past (e.g. Meteor) but they can be a good option for some.

Hapi.js commonly referred to as "hapi," is an open-source web application framework for building web and application server systems in Node.js. It was created by Walmart Labs and is designed to provide a flexible and robust foundation for building web applications, APIs, and other networked software.

Hapi – The Simple, Secure Framework Developers Trust

Hapi.js is one of the best Node.js web framework, which is used for developing application program interfaces. Thanks to a strong plugin system Hapi.js, you can fully manage the development process. Hapi.js motivates the devel­oper to focus on the reuse logic instead of spending time building the infrastructure.

does not seem so https://github.com/hapijs/hapi/releases/tag/v21.0.0 (ok, I'm nitpicking on that one)

Joi validator used to be part of hapi but then became a standalone library that you can use everywhere where validation is needed. So for example, here's how username validation can be done:
